| 目的 比较CT 和MRI 诊断胆囊腺肌瘤病( GBA) 的作用与限度。方法 分析19 例经组织学证实的GBA 患者的CT 和MRI 资料,比较常规T1WI、T2WI、3 mm 薄层T2WI、MRCP、平扫CT、螺旋CT 胆道造影( SCTC) ,以及CT 和MRI 动态增强扫描各时相图像显示罗2阿窦和胆囊病变的能力。观察结果与病理标本所见对照。结果 19 例GBA 包括局限型11 例,节段型5 例,弥漫型3 例。MRI 显示罗2阿窦优于CT。胆汁显著浓缩时,SCTC 可补充MRCP 的不足。结论 MRI 诊断GBA 的作用优于CT。 |

| Objective To compare the role of CT and MRI in diagnosing adenomyomatosis of the gallbladder (GBA) basedon imaging-pathologic correlation. Methods Pre2and post2cont rast CT and MR imaging of 19 patient s with GBA were stud-ied. For each patient, 5 pulse sequences were performed in a 1. 5T system , including axial 7 mm T1WI and T2WI, 3 mm thin-slice T2WI, MRCP and FSPGR t riple-phase dynamic study; plain CT , dynamic CT and spiral CT cholangiography(SCTC) were also obtained for comparison. Two radiologist s evaluated CT and MR images. Results Gallbladder wall thick-ening was visualized in all patients, the thickness was f rom 5 to 13 mm (mean 8 mm) . Among them , 11 fundal type , 5 seg-mental type , and 3 diffuse type of GBA were identified. Rokitansky2Aschoff sinuses (RAS) were seen in the thickened gall-bladder wall and their sizes ranged f rom 3 to 7 mm (mean 4 mm) . MR imaging was superior to CT in showing RAS. SCTC was complementary to MRCP in showing RAS and contour of the gallbladder as highly concent rated bile existed. ConclusionMR imaging was superior to CT in diagnosing GBA. |
